Side effects

Possible side effects when taking an erectile dysfunction medication include pain in your back/muscles/head, migraines, getting flushed/going red, indigestion, feeling and or being sick, getting a blocked or runny nose and vision disturbances.

Risks

Erectile dysfunation medications may not be suitable for you if you have been told not to have sex, not to engage in sexual activity/actions that widen your blood vessels, have low blood pressure (hypotension), have recently had a stroke, have unstable angina, have had a heart attack or have a history of non-arteritic anterior ischaemic optic neuropathy. Men with cardiovascular disease/anatomical issue with their penis/priapism/taking long-lasting alpha-blockers should use with caution and discuss with a doctor first. Do not mix with drugs/medications containing nitrates.

When a man becomes sexually aroused, his brain sends nerve signals to his penis causing an erection (the nerves increase the blood flow to the penis and the tissue expands and hardens). Erectile dysfunction, sometimes referred to as ED or impotence, is when a man cannot get or keep a firm enough erection to have satisfactory sex. The term can also refer to a lack of sexual desire (a reduced libido). Erectile dysfunction treatment can help men achieve an erection and enjoy sex. Which treatment is best depends on what is causing the problem.

Erectile dysfunction is very common and is thought, in some way, to affect roughly 50% of all men aged 40-70. Erectile dysfunction is very different to issues with ejaculation (for example, premature ejaculation – where arousal, orgasm and ejaculation happen quickly.)

Overview

Buying Cialis Online

You can buy Cialis online from our UK registered online pharmacy and doctor service. Cialis is a treatment for erectile dysfunction, containing the active ingredient Tadalafil. Cialis and all ED medications should be used responsibly, and only by those who suffer from dysfunction.

To order Cialis online, you will need to complete a medical assessment so our doctors can assess your suitability for this treatment. If your order is approved, a prescription is passed to our UK registered pharmacy, who will dispense and deliver your order.

Cheaper Generic Cialis

Tadalafil which is the active ingredient in Cialis is now available generically. In 2017, the patent for the exclusive manufacture of this drug expired, and so Lilly were no longer the only company able to market this medication. When a patent expires, prices will often drop drastically, making medications more affordable for patients and the NHS.

'Generic Cialis' is medically equivalent to Cialis, and contains Tadalfil, the same ingredient. It is Tadalafil which works to increase blood flow to the penis to help achieve an erection.

Cialis Summary

Taking Cialis

Take one tablet about 30 minutes before sex. The effects of Cialis can sometimes be noticed as soon as after 30 minutes, and last for up to 36 hours.

Never take more than a ONE tablet within 36 hours

Although Cialis can be taken with food, this may slow down the time it takes for the drug to work.

How it works

Cialis works by increasing blood flow into the erectile tissue of the penis. Cialis does not have an impact on libido, only your ability to get and maintain an erection when sexual aroused.

Effectiveness

Most men will notice a firmer and longer-lasting erection. If the treatment does not work, ask our doctors (or your own GP), whether it would be appropriate to increase the dose. Alternatively, they may recommend another treatment.

If Cialis doesn’t work for you first time round, it could nevertheless be more effective next time. Doctors often advise trying all erectile dysfunction medicines eight times before giving up.

Side effects

While side effects are uncommon, they can include nausea, vomiting and diarrhoea. Cialis can also cause nasal congestion, headaches, facial flushing, slight vertigo, a pounding heartbeat and blurred vision.

Nitrates and Cialis

Cialis can not be prescribed by our doctor if you are taking nicorandil or nitrate based medication, such as GTN spray or isosorbide mononitrate tablets for angina.

Alpha-blockers and Cialis

If you are taking alpha-blocking medicines, such as tamsulosin or trazodone, you are advised to leave at least six hours between taking your alpha-blocker and Cialis.

About Cialis

What It Does

Cialis is part of a group of drugs called PDE5 inhibitors. These drugs work by increaseing the blood flow to your penis when sexually stimulated. For men who are unable to achieve a sufficient erection for penetration, Cialis and the other erectile dysfunction drugs have proven highly effective. They have helped millions of men have normal sex lives.

Why Choose Cialis

The main reason many men may choose Cialis over the other ED drugs available, is it's long lasting effect. Tadalafil can be effective for up to 72 hours after dosing, and so men may be able to have regular sexual activity for 3 days after taking a dose. Wihle many patients who used Cialis have now chosen to use the generic form, there is still a brand recognition with the original Lilly product, and men will still choose Cialis over Tadalafil for this reason.

The Wekend Pill

Due to this long lasting effect, Cialis has become known as "The Weekend Pill". This long lasting effect is the distint difference between Viagra and Cialis, and the reason why men will select Cialis over the other PDE5 inhibitor drugs available.

Cialis Daily

More recently, Cialis has become available as a daily dose in 2.5 and 5mg strenghts. Men may consider using the daily dosage if they have found the 'when required' dosage effective. The reason the daily form of the drug is advantageous is that men no longer need to always remember to take their cialis dose 30 minutes before sexual activity. The daily dose is taken each day, and maintains levels of Tadalafil in the blood. This means that an erection should be achived at any time of day or night, without needing to remember to take your medicatoin just before. This daily tablet is particularly useful for men with a highly active sex life.

Initial Dosage

The recommended starting dose of Cialis is 10mg, 30 minutes before sexual activity. If unsuccessful, the dosage can be increased to 20mg. A second dose should not be taken however within 72 hours of the first. It it advised that any ED medication should be taken several times, before deciding to try another, as it may not work first time.

Cialis Alternatives

Drug alternatives to Cialis include the famous blue pill, Viagra. Sildenafil is a generic form of Viagra, which is cheaper but contains the same active ingredient. Spedra and Levitra are two other ED drugs also available in the UK.

Some men may also find that counselling is effective in treating their ED. For men whose erectile dysfunction is mainly down to nerves, or some other form of anxiety, psychologists can assist in developing techniques to better cope with situations where stress occurs. This in turn, can help improve your sexual performance.

Lifesyle changes can also help some men to overcome erectile dysfunction symptoms. Obesity and alcohol are both factors in erectile dysfunction, and decreaseing your alcohol intake, and exercising more, can have a positive impact on your ability to get and maintain an erection.
